TJ-100 Engine Frequently asked questions:

 

Q: What is the PBS TJ-100 engine off of?

A: It isn't really 'off of' anything. PBS has a long history of turbine machinery design. The TJ-100 turbine (jet) engine is based on the APU designs built for aircraft and helicopters. Some parts of this engine have been in production for years. PBS recognized a market for a small thrust (not turboshaft) engine for use in UAV's and light manned aircraft. Their engineers designed the TJ-100 for these markets. The engine is in current production, and is composed of new components.

 

Q: What is the thrust of the TJ-100 engine?

A: Maximum static thrust is between 225 and 247 pounds (1000 - 1100 N), depending on the particular version and configuration of the exhaust, intake and engine controller programming. Continuous thrust is approximately 70% of maximum. More thrust may be available for specific applicaions, but engine life will be reduced.

 

Q: What is the weight of the TJ-100 engine?

A: The TJ-100 engine weighs approximately 42 pounds (19 kg), including the integral engine controller & fuel and oil pumps. Weight will vary slightly depending on configuration and accessories.

 

Q: What is the fuel burn rate of the TJ-100 engine?

A: The TJ-100 engine has a specific fuel consumption of 1.09 lbm/lbf/hr at near maximum thrust. This equates to approximately 40 gallons/hr at 247 pounds thrust. Click here for the performance chart.
